Abstract

The invention provides an arc plasma torch and relates to a plasma heating device. The arc plasma torch is characterized in that the torch is composed of a positive pole, a combined negative pole, a torch barrel and a back seat, wherein the positive pole, the torch barrel and the back seat are arranged in a coaxial mode, the back end of the torch barrel is connected on the back seat to form a torch body, the positive pole is connected at the front end of the torch barrel, a loop core space of the positive pole forms a nozzle, an inner space of the torch barrel forms an air chamber, and the back seat forms a back closed end of the torch barrel; the positive pole is of a hollow ring form structure, a ring-form cooling groove is arranged in the ring form, and the ring-form cooling groove is connected with a cooling water port; and the combined negative pole is composed of a negative pole rod, a negative pole head and a negative pole cap, the portion from the middle to the front end of the negative pole rod is of a tubular structure, a cooling cavity is formed in the space in a tube, the front end of the negative pole head is a reduced circular conical surface, and a back portion solid of the negative pole head is provided with a driving water gasification hole or a vaporization fin. The arc plasma torch is used in a gasification device, the efficiency of the torch reaches nearly 100%, and the arc plasma torch can effectively protect the negative pole and the negative pole from being ablated.

Description

technical field [0001] The invention relates to electric heating equipment, in particular to a plasma heating equipment. Background technique [0002] At present, plasma technology has been widely used, industrially used in plasma ignition, plasma spraying, metal smelting, plasma heating to manufacture nanomaterials, cutting, garbage incineration and waste treatment, etc. In recent years, the technology of using plasma to treat dangerous and harmful wastes and household garbage has developed rapidly. The plasma treatment method is quite different from the general incineration method. This state, accompanied by the discharge phenomenon, will generate active chemicals of excited atoms, excited molecules, dissociated atoms, free atomic groups, atomic or molecular ion groups, and their collisions with other chemical substances. In the plasma generator, the discharge effect causes the working gas molecules to lose the outer electrons and form an ion state, which generates high t...
